According to the physique of China people and the influence of body-building exercise on human body shape and physique, bodybuilding experts in China have studied and summarized the calculation methods of standard measurements for women: bust = height (cm) ×0.535, waist = height (cm) ×0.365 and hip = height (cm) ×0.565. The actual calculated index and the standard index of 3 cm are standard. Less than 5 cm means too slim (thin); More than 5 cm indicates that it is too plump (overweight).
